Pipe cleaner



Patented Dec. 10, 1946 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to pipe cleaners and more particularly to thattype of pipe cleaner adapted for the rinsing out or cleansing of thebowls and stems of pipes or the like.

A primary object of this invention is the provision of an improved pipecleaner adapted to be utilized in conjunction with a variety of sizes ofpipe bowls, as well as a variety of sizes of faucets or the like.

Another important object of this invention is the provision of such apipe cleaner which may be utilized to cleanse the stems of the pipesseparately from their bowls, and which may be likewise used to cleancigarette or cigar holders or the like.

Still another object resides in the provision of an improved pipecleaner facilitating the complete cleaning of sediment and nicotine fromthe bowls and stems of pipes and similar articles.

Other objects will in part be obvious and in part be pointed outhereinafter and shown n the accompanying drawing, wherein there isdisclosed the preferred embodiment of this inventive concept.

In the drawing:

Figure 1 is a side View partially in section and partially in elevationshowing the device of the instant invention as applied to a faucet and apipe, and

Figure 2 is a front view partially in elevation and partially in sectiondisclosing the device of the instant invention as applied to the stem ofa pipe, the bowl being removed therefrom.

Like reference numerals refer to like parts throughout the several viewsof the drawing.

Having reference now to the drawing, it will be seen that the device ofthe instant invention, generally designated at I0, is comprised of abody portion II of suitable resilient material such as medium softrubber the lower portion of which terminates in a nipple or conicalportion I2, The body portion I I is provided interiorly with a conicalrecess I3, the upper portion of which terminates in annular groove I4. Abore I5 tapered inwardly toward the base of conical recess I3communicates with the recess and the exterior 2 of conical ornipple-shaped portion I2. A peripheral iiange I6 surrounds the body atan intermediate point.

Now from the foregoing the operation of the device should be readilyapparent. The device is rst placed over a faucet, the annular groove I4being of a dimension designed to accommodate ordinary average sizefaucets of relatively large diameter. However, in the event that thefaucet utilized is smaller it will be seen that the conicalshapedportion I3 accommodates the same to seal the device tightlythereagainst.

A pipe bowl I8 is then adapted to be seated against the flange I6, andwarm water or steam admitted from the faucet 2B. It will thus be seenthat this action thoroughly cleanses the pipe bowl and the stem if thesame is associated therewith during the cleansing operation.

For better cleansing of the stem, however, the same may be separatedfrom the pipe bowl and inserted in the bore I5 (see Figure 2), thenormal resiliency of the material of the device holding the same firmlyin position during the operation.

From the foregoing it will now be seen that there is herein provided adevice accomplishing all the objects of this invention and othersincluding many advantages of great practical utility and commercialimportance.

As many embodiments may be made of this inventive concept, and as manymodications may be made in the embodiment hereinbefore shown anddescribed, it is to be understood that all matter herein is to beinterpreted merely as illustrative and not in a limiting sense.

I claim:

In a cleaning device for pipes, a body portion of resilient materialhaving a conical recess therein terminating at its outer extremity in anannular groove, said body portion terminating in a conical extremityhaving an inversely tapered bore therethrough connecting with saidrecess, and a peripheral flange about said body, adapted to seat on therim of a pipe bowl.
